Mapping Matrix fields to paginated feed when matrix block field does not appear on first page of feed

[rob-c-baker]

Description

When importing a feed from a URL (in this case a JSON based feed) Feed Me populates the drop downs for selecting the fields to map based on hitting the feed URL to get the fields contained.

This is an issue with larger paginated feed URLs when the Matrix field we need to map has block fields that need to be imported but they do not appear on the first page of the paginated feed.

Suggestion

It is impractical for FeedMe to go through all pages of a feed looking for Matrix block fields that may or may not be present. Instead, perhaps on the mapping screen, in addition to the drop down to select mapped fields, there is the opportunity to manually type in field references in the style shown in the drop down, i.e. [matrix-field-name]/[sub-field-name]

Steps to reproduce

1. Set-up a feed with a URL that uses the pagination feature
2. Ensure the source feed URL has fields that need to be mapped to the Matrix field that do not appear on the first page of the feed
3. Look at the mapping screen - the fields not on the first page are not available to map and therefore don't get imported when the feed is run
